SPRING VIINDER PHONCGR-APH'MOTORS.

Application filed'a'anuary 16, .1924. Serial No: 686,662.

To all whom it'moy concern:

Be it knownthat I, Josn-rrr' It. LA Riviiinn, a .subj ect of the King ofGreat Britain re siding at Waterways, in the Provincerof Alberta and.Doininion of Canada, {have invented new and useful Improvements-inSpring Winders for Phonograph Motors, of which the following is aspecification.

The object of my saidinvention is the pro- -l0 vision of a peculiarandadvantageousdevice for bringing about the winding of; the spring of amotor employed forthe rotation of the record table of a phonograph.

"To the attainment .oftheqforegoing, the

.invention consists in the improvement as hereinafter described 1 anddefinitely claimed.

In the accompanying drawings, forming part of this specification Figure1 is a. View partly .in' elevation and partly in section showing aportion of a phonograph and. my novel device arranged in properrelation'to the spring motor of the phonograph.

Figure 2'is an enlarged diam'etrical section of mylnovel device, the,same being shown as properly arranged relative to a part of the springmotor.

Figures 3 and 4: are transverse sections taken in the planes indicatedby the lines 33 and 1-1, respectively, of Figure 2.

Similar numerals of reference designate corresponding parts in all ofthe views of the drawings.

The phonograph 1 is of the ordinary or any other suitable constructionas is also the spring motor 2 for rotating the record table 3, the saidspring motor including the usual socket member 41, interio-rly threadedas shown in Figure 2 and appropriately supported in the phonograph.

In accordance with my invention the horizontal wall 1 of the phonographor phono graph casing is provided at 5 with a ver tically disposedaperture, and also in accordance with my invention my novel windingdevice is disposed under the said hori- Zontal wall 1 and entirelywithin the phonograph casing 1 so as not to offer any obstruction fromsaid casing 1.

My novel device per se is best shown in Figures 2, 8 and 4-, and byparticular reference to said figures it will be observed that a threadedshaft 6 is disposed in the threaded socket member 1 which member 1 is inconnection with the spring motor 2 in the ordinary well known manner.The shaft 6 is carried through the apertureo in thecasing wall 1* and 1sprovidedwith afinger-piece carried by a body?' which is pre ferably ofthe body 7 remote from the shaft (tie a socket 8 of circular form'in'cross-:seotioi1which 0 1 1- which as shown by full" lines in Figure 1is adapted to bring up against the said wall 1* and tonormally-rest-thereagainst. Surrounding theshaft Q and arranged 313111116 :outer side thereof 1n-a housing 15*is a convolute spring 16.'Thehouslng =15 is"fiXe'd with respect to thedrum '12, and-one'enc'bofthe springlo is connected tothe shaft 9 while the other and outer endofthe spring is connected to thehousing 15,. ln'thiszeonnection it will beobserved ithat the housing 15 is opposed to a closure disk 17, looseabout the shaft 9, and that the outer end of the said shaft 9 is fixedagainst rotation in and supported by a bracket 18 pendent from thecasing wall 1*.

At 19 the casing 1 is provided with a cover which may be and preferablyis hinged in the ordinary manner.

In the practical use of my novel winding device it will be understoodthat normally the cable 13 and its finger piece L1 will be arranged asshown by full lines in Figure 1, it being simply necessary when it isdesired to wind the spring of the motor 2 for the operator to grasp andpull the finger piece 1 1 upwardly to the position shown by dotted linesin Figure 1. When the finger piece 141 and cable 13 are pulled upwardlyas stated, the drum 12 will be rotated in one direction against theaction of the spring 16, and a portion of the cable 13 will be led offof the drum 12, the said rotation of the drum 12 acting through the pawl11 and the ratchet 10 to rotate the body 7 and through the body 7 thebefore mentioned member 4 to wind or tension the spring of the motor 2.When the finger piece 14c is released the spring 16 will operate to turnthe drum 12 in reverse direction so as to bring about the taking up ofthe cable 13 on the drum 12 and the restoration of the finger piece 14to the position shown by full lines in Figure 1. By repeating theoperation described, the spring of the motor 2 maybe expeditiously andeasily wound or tensioned to the extent desired. It will also beapparent that my improvement obviates the necessity of employing a crankor any other unsightly projection in conjunction with the phonograph.

I have entered into a detailed description of the construction andrelative arrangement of the parts embraced in the present and preferredembodiment of my invention in order .to impart a full, clear and exactunderstanding of the said embodiment. I do not desire, however, to beunderstood as confining myself to the specific construction and relativearrangement of parts inasmuch as in the future practice of the inventionvarious changesand modifications may be made such as fall within thescope of my invention as defined in my appended claims.

Having described my invention, what I claim and desire to secure byLetters-Patent,

1. The combination in a phonograph, of a spring motor for rotating arecord table, said motor including a rotary member having a threadedsocket, a body having a threaded shaft dis osed in said member and alsohaving a soc et in its opposite end, a casing in which said motor andsaid body are arranged, a shaft supported in the casing and alsosupported in said body and held against rotation, a ratchet fixed withrespect to the body and loosely surrounding the shaft, acircumferentially grooved drum loosely surrounding the shaft andcarrying a spring pressed pawl arranged to cooperate with said ratchet,a cable connected to and adapted to be wound on said drum and extendingthrough an aperture in a wall of the casing, a finger piece on saidcable and adapted to bring up against said wall, a housing fixed to thesaid drum, a convolute spring in said housing and connected at its innerend to the shaft and at its outer end to the housing, and means loose onthe shaft for closing said housing.

2. The combination of a phonograph casing, a shaft mounted therein andheld against rotation, a spring motor in the casing and having a rotarymember in connec tion with its spring for the winding or tensioning ofthe spring, a body rotatable about the shaft and connected with saidmember, a ratchet fixed to said body, a drum loose on the shaft andhaving a pawl opposed to said ratchet, a spring surrounding andconnected to the shaft and also connected to the drum, and a cablesecured to and adapted to be Wound on the drum and extending through anaperture in a wall of the casing and having a finger piece adapted tobring up against said wall.

In testimony whereof I affix my signature.
